Area Forecast Discussion National Weather Service Tucson AZ 350 AM MST Wed Dec 11 2019
SYNOPSIS. Dry conditions with passing high clouds at times and a warming trend will prevail through Saturday. A disturbance moving north of the area may bring a few rain and snow showers Sunday and Sunday evening to the White Mountains. Otherwise, continued dry conditions but with cooler temperatures Sunday into Monday.
DISCUSSION. Upper trough axis early this morning extended from the Pacific Northwest southwestward to just west of northern Baja California early this morning. Ahead of this trough axis, mainly cirriform clouds were producing partly cloudy to cloudy skies across southeast Arizona. The upper trough axis will move rapidly eastward into the central and southern Rockies by this evening. As a result, expect clearing skies from west-to-east this afternoon followed by clear skies to mostly clear skies tonight.
However, additional higher level moisture upstream will bring more albeit not quite as thick cirrus clouds to the area on Thursday. High pressure aloft is progged to briefly amplify Friday near the southern California/northern Baja California coasts. Expect sunny skies to mostly sunny skies Friday as the bulk of higher level moisture is shunted north of the area.
The upper pattern will transition on Saturday to a fairly fast zonal flow regime in response to a shortwave trough digging across the Pacific Northwest. Thus, continued dry conditions Saturday but with more clouds likely versus Friday. Various 11/00Z models depict some amplification to an upper trough Sunday over the Four Corners region. There were some timing differences between the deterministic GFS/ECMWF regarding the progression of this trough into the central CONUS by Monday. As a result, the potential starting/ending times for a few rain/snow showers vicinity of the White Mountains is questionable at this time.
Have opted for isolated rain/snow showers to occur across the White Mountains Sunday into Sunday evening. Regardless of the exact timing for potential precip, any rain amounts and snow accumulations will be very light and essentially inconsequential. Some westerly breezes may occur Sunday afternoon with the passage of this trough. Thereafter, dry conditions area-wide Monday into Tuesday as high pressure aloft moves into the western states. Some gusty east winds may also prevail next Tuesday in response to a backdoor cold front and a somewhat tight surface pressure gradient.
High temperatures this afternoon will be a few degrees warmer across eastern sections versus Tuesday, but will be nearly identical to temps achieved Tuesday from Tucson westward. Expect a degree-or-two or such of warming Thursday followed by about 3-5 degrees of additional warming on Friday. Similar high temperatures should prevail Saturday versus Friday, then a cooling trend is on tap Sunday into Monday. Slightly warmer temperatures should return next Tuesday.
AVIATION. Valid through 12/12Z. Expect scattered to overcast clouds above 25k ft MSL into early this afternoon, then mainly few to scattered clouds above 25k ft MSL later this afternoon into Thursday morning. Surface wind variable in direction mostly under 12 kts across much of southeast Arizona. However, some brief ely/sely gusts near 15 kts may occur late this morning vicinity KTUS and KSAD. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Dry conditions through next Tuesday except for a few rain and snow showers Sunday and Sunday evening across the White Mountains. A warming trend will occur especially by Friday and Saturday before cooler temperatures return Sunday into Monday. 20-foot winds will be terrain driven less than 15 mph through Saturday. Some gusty west winds may occur Sunday afternoon, and locally gusty east winds may also prevail next Tuesday.
TWC WATCHES/WARNINGS/ADVISORIES. None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
